veniently moved by the right and left hands of the operator. Where two drums are operated by a driving-shaft intermediate thereto it does bring the hand-levers into such interference, but the projection of brackets outwardly from the two drum-bearings sets the lever-pivots at the desired distance apart to avoid any interference. W'hre the shaft of one drum is set lower than the other upon the hoister-irame, as is common to permit the passage of the hoisting-rope over the forward drum, the use of such bracket serves also another purpose, in permitting the pivot of the hand-lever for such lower drum-shaft to beset at the higher level, by inclining the bracket upwardly us well as outwardly from the lower drum-bearing. Such inclination may bring the pivots of the hend levers at nearly the same level. W'hen it is necessary to lock the hand-lever in its adjusted position, a locking segment ismounted upon the bracket concentric with the hand-lever pivot.

The construction will be understood by reference to the annexed drawing, in Whichv Figure l is a side elevation of the hoister pmvided with he im .rovem nts; g- 2 i v a plan of the same; Big. 3 is a plan of one of the brackets and its connections, in section where hatched near the center line of the screw; Fig. t is a front elevation of the same, parts; and Fig. =5 is an edge YlQW of the connection between the hand lever and its crank-arm.

G- Seth lawter y t e u ie we; a l uiifiqrew a or e sthseeied, we w in t est e all mee I. h W dimeusl n mg ern r t e e uns 29str g engin .re kee f and f are fitted to the outer ends of the claws, being formed of flat ribbed arms provided at their outer ends with the pivots (Z and d for the handlevers h and h, and secured by bolts extended through the foot of each bracket and the adjacent claw into the outer end of the bearing, as shown at g in Fig. 3. Each of the screws is shown with a crank-arm 71 secured adjustably thereon as is common, and each ofthe hand-levers is shown with a crank-arm is extended beyond the pivot and coupled to the crank-arm z'by a link j.

The hand-levers h and it have each an adjustable split-socket connection with the hub In of its crank-arm 7:, by which the hand-lever may be set into different rela'- tions to such'crank-arm so as to bring the hand-lever into convenient position for the operator. This is illustrated in Fig. l, where the crank-arm is upon the hand-lever h is shown in a line with such hand-lever, while the crank-arm it upon the hand-lever h is shown at an angle with the hand-lever, so that each may be moved through an are convenient for the operator. The crank-arm i is similarly adjustable, to vary the screwpressure.

-. cate the same.

- Notched segments Z are secured upon each of the brackets concentric with the handlever pivot, being bolted to studs m formed respectively upon vthe body of the bracket and upona lugn'extended from .near the pivot, as shown in Figs; 3 and 4. I

The hand-levers are as usual provided in practice with spring-latches v to engage the notches of the segments, the only novelty in. this, part of the construction consisting in.

the support of the segment upon the bracket i concentric with the hand-lever pivot. The

mounting of the segments upon the brackets makes the bracket and segment an attachment which may be applied to the claw of a drum-bearing when first constructed, or at .any time after it has been in use, to secure the advantages of the present invention.

The Link j-is shown materially longer than the distance between the centers of the hand-.

lever pivot and the screw, and the crankarm 2" upon the screw is shown somewhat longer than the arm 7: upon the hand-lever. These proportions cause the screw to move much more rapidly than the hand-lever when loosening the screw, as is indicated by fixed position.

the dotted lines h, k and i in Fig. 1. These dotted lilies show the arm 10 exerting its full le\'erage,'while the arm 2' is approaching its (lead center and therefore making a circular movement more rapid than that of the bracket-arm 7c.

The screw a requires to be made with a screw-thread reverse to that on screw a, as its hand-lever projects in the opposite direction, and turns the screw to the left when pressed downward to tighten the clutch. Such downward movement of the lever h throws the crank-arm 7.; nearly on its dead center, while the crank-arm 2' upon the screw has its greatest leverage, thus giving the screw a short movement but greater force, when closing the clutch.

Dotted circles 0, 0', in Fig. 1 show that the paths of the handles upon the levers h, h, clear one another, whereas the handles would overlap more than two-thirds of their length if they were placed directly upon the screws a, a, and projected toward one another. as it is necessary for the operator tov manipulate them both while standing in a The location of the handlevers upon pivots apart from the screws thus not only brings the hand-levers in a more convenient position for the operator, bnt-afi'ords the opportunity of linking the hand-levers to the screws, so as to produce the desirable differential movement.

The throttle-lever p is shown mounted adjacent to the paths of the two levers h, It, so as to be readily reached by the operator, but its connection with the steam-throttle is not shown. as it forms no part of the present invention. I

In Fig. 2, two brakelevers u are shown between the frame A and the handlevers h, h, such'brake-levers being commonly arranged near the lower edge of the bed where they may be reached by the 0porator and worked by his feet when stand- .de tachably upon the outer end of the claw and projected laterally therefrom, and the said claw having a bearing for the head of the screw outside of the thread in the claw, a pivot upon the bracket and a hand-lever mounted. upon such pivot, crank-arms attached to the hand-lever and to the screw outside of the bearing in the bracket, and a link connecting such crank-armsand operating to turn the screw-head in its bearing.
